JACQUARD APPARATUS Application filed January 21, 1930, Serial No. 422,423, and in Germany January 28, 1929.

The pattern cards which are used in connectlon with textile machines, particularly with circular knitting with acquard pattern arrangements are several metres long as a rule and hang down from their turnable cylinder at the side of the machine. Supervision of the machine and access to many parts thereof are made much more diflicult thereby.

19 According to the invention the cards of a jacquard pattern card chain are folded after they have run off the turnable cylinder and are stored in that state on a slide track until they again come into employment. Owing to the laying together of the cards in folded state when not in use very little room is required for their storage and if the said slide track is provided in the immediate vicinity of the turnable cylinder for the jacquard card chain, which cylinder mostly is arranged above the machine, a good supervision of the machine is attained thereby.

The device for storing the inoperative cards in a folded state may take verydifferent forms. According to the invention the turnable cylinder is provided with drivers at two opposite places of their end surfaces, which drivers act on a finger in such a manner that the finger, either indirectly or direct- 39 ly moves every second card in a direction different from its normal direction of movement, whilst a slide track carries the thus folded juXta-positioned cards and allows them automatically to again leave the track.

In the accompanying drawings, which shows one constructional form of the invention by way of example- Figure 1 shows the folding device before the commencement of its operation.

Figure 2 shows the folding device after it has begun its operation, and

Figure 3 shows the turnable cylinder in ide view.

Referring to the drawings, the turnable cylinder 2 is rotatably mounted 011 the machine frame 1 and at the same time there is secured at each end of the cylinder a small bracket 3, a spindle 5 being rotatably mounted in the eyes 4 of these brackets 3. On the end of the spindle 5 is mounted a finger 6 to the path of movement of the finger 6. On

oscillate therewith, the finger being bent towards the rear and pressed against the spindle 8 of the turnable cylinder by a spring 7. A plurality of tines 9 are secured to the spindle 5. At each of two opposite places on one end of the turnable cylinder 2 a driver is provided in the form of a latch '10 and 10 respectively which lie in rotation of the turnable drum 2 in the direc- 6o tion of the arrow, these latches push against the finger 6 and drive the same to the furthest extent. The tines 9 thereby move in the same direction and force outwards the card which lies in front of them so that it comes to lie against the previously stored card. Hereupon the finger 6 together with the tines automatically returns to its position of rest and, because during the next partial rotation of the cylinder 2 there is no actuation of these parts owing to the absence of a driver 10, the following card, in accordance with its depending position, will lay itself automatically against the preceding card. These cards 11 are caught'and stored by a sheet metal segment 12 which is slightly inclined downwards.

Owing to the slightly rearwardly inclined slide track 12 the cards 11 laid in folds automatically slide always forwards, so that stemming of the folding device cannot arise. The forwardly advanced cards 11 are then taken over rollers 13 and again presented to the turnable cylinder 2.

We claim-- 1. In jacquard apparatus, a rotatable cylinder and a chain of pattern cards adapted to pass over the cylinder, in combination with a slide track on which the cards are stored in a folded state and means on the cylinder cooperating therewith for folding the cards onto the track.

2. A device according to claim 1, comprising drivers provided at two opposite places on the turnable cylinder, and finger means actuated from the drivers and acting on every other card in a direction different from the natural direction of movement of the cards.

3. A device according to claim 1, com- 100' prising drivers provided at two opposite places on the turnable cylinder, finger means operated by the said drivers, and tine means operatively connected to the finger means 5 and moving every other card in a different direction from its natural movement.

In testimony whereof, We have signed our names to this specification this 24; day of December, 1929.
